Access is being provided initially to a restricted… Read More

ESnet is developing and deploying a prototype service that enables on-demand provisioning of guaranteed bandwidth, secure virtual circuits within the ESnet production network. The service, called OSCARS (ESnet On-Demand Secure Circuits and Advance Reservation System), is designed specifically to meet the science discipline-driven network requirement of dynamically provisioned quality of service… Read More

When the International Grid Trust Federation (IGTF) was established in October 2005 during the 15th Global Grid Forum (GGF) in Boston, much of the groundwork for the project had been laid by ESnet over the past three years. With the establishment of the ITGF, users of Grid computing worldwide took a step closer to accessing computers and information in 50 countries in Asia, the Americas and… Read More

ESnet will install at least 44 new 10 Gb/s circuits and connections in 2005‑06. Half of these were completed and in production by November 2005, and the remaining connections should go into production by the end of spring 2006. By comparison, only five 10 Gb/s links were in place in January 2005.
These new connections are part of a new architecture that will provide 20‑40 Gb/s metro area… Read More

DOEGrids Certificate Authority (CA) entered its fourth year of operation in December 2005 with about 3,500 active certificates, making DOEGrids one of the largest certification authorities in Grid computing. The growth of service and host certificates continues to outpace user certificates.
DOEGrids is supporting development of new technology to improve the usability of DOEGrids PKI by its… Read More

ESnet Director Bill Johnston lays out his vision of ESnet’s new directions in a two-pager, explaining that meeting DOE’s science needs “ entails not only increasing end-to-end bandwidth, but becoming actively involved with other domestic and international research and education (R&E) networks in developing and deploying cutting edge operational technologies. Such collaboration is… Read More

BERKELEY, Calif. ‑ The U. S. Department of Energy’s Energy Sciences Network (ESnet), which supports the large-scale science and large-scale collaborations of DOE’s Office of Science, has taken the first steps to implement a new network architecture that will increase the reliability and dramatically boost the bandwidth available to the DOE research community.
The new architecture is… Read More

BERKELEY, CA. – Responding to the increasingly data-intensive demands of the scientific community, the U.S. Department of Energy’s (DOE) Energy Sciences Network (ESnet) is implementing a new architecture of connected Metropolitan Area Networks (MAN).
ESnet, which is managed by DOE’s Lawrence Berkeley National Laboratory, is a high-speed network serving thousands of DOE scientists and… Read More

DENVER, September 27, 2004 — Qwest Communications International Inc. will upgrade network connectivity into two U. S. Department of Energy (DOE) sites on the Energy Sciences Network (ESnet). Qwest’s continued work on ESnet is part of a seven-year contract, which began in 2000 and has a potential value of more than $80 million.
Under the contract, Qwest will increase ESnet’s bandwidth by… Read More

Bill Johnston, a distinguished networking and computing researcher, was recently named Manager of the Energy Sciences Network (ESnet), a leading-edge, high-bandwidth network funded by the U.S. Department of Energy (DOE), Office of Science. ESnet is managed by DOE’s Lawrence Berkeley National Lab.
ESnet is used by thousands of scientists and researchers worldwide, and provides a high-end… Read More

William E. “Bill,” Johnston, an LBNL senior scientist who has worked in the fields of networking and high-speed distributed computing since the creation of the Internet, was appointed this week as the project manager for the Energy Sciences Network (ESnet), effective immediately.
ESnet is a high-speed network serving thousands of Department of Energy scientists and collaborators worldwide. Read More

The Energy Sciences Network (ESnet), the high-performance network funded by the U.S. Department of Energy’s Office of Science, has just completed an upgrade to 2.5gigabits (billions of bits or Gbps) per second and 10Gbps in the highest speed portion of the network.
Typically, a new generation of data communications bandwidth consists of a fourfold increase in performance. ESnet’s new 10Gbps… Read More

The U.S. Department of Energy’s Energy Sciences Network (ESnet) recently teamed with Juniper Networks to become one of the very first networks to run both IPv4 and IPv6 simultaneously on a large-scale production network connecting hundreds of thousands of scientific researchers around the world.
The successful rollout of the next generation Internet Protocol, known at IPv6, in parallel with the… Read More

The Department of Energy’s Energy Sciences Network (Esnet) this week announced that it has awarded a $50 million contract to Qwest Communications International Inc. to support ESnet for up to seven years.
Under the contract, Qwest will provide performance levels up to a terabit (one million megabits/second) network by the year 2005, offering 500 times the highest speed available in the… Read More

A few years from now, the Internet could become a victim of its own success. Its dramatic growth -- often cited as 15 percent growth per month in number of users connected and as much as a factor of 10 growth per year in Internet backbone bandwidth required to support them — could overburden the current infrastructure, resulting in networks held together with cyber baling wire and virtual glue.
